The Gap-Down Continuation Set-Up
A stock opens well below its range on a repricing it cannot recover from, and the first half-hour's low becomes the reference the rest of the session is read against.

What to take away
- The mirror of the gap-and-go, and the more violent one: down gaps are wider and faster.
- The opening range low is the price the set-up completes through; its high is where the reading stops holding.
- Recovering the gap is the failure case, and a recovered down gap tends to run hard.
- Down gaps on a broad market shock behave completely differently from down gaps on company news.
- A gap that halves within the first hour has already failed, whatever it does afterwards.

The down gap that keeps going
The bearish mirror of the gap-and-go, with the widest failure in the catalogue. Why an unfilled gap above is the thing that makes it dangerous.
This lesson is part of a Stock Alerts + Tools plan.
The shape
A stock that has been trading in a range opens sharply below it, well clear of the previous close, and then fails to recover any meaningful part of the distance. It builds a small range low down, holds under it, and leaves from the bottom of that range rather than climbing back toward the gap.
The bearish mirror is not symmetrical in temperament. Down gaps are typically larger, because the news that causes them is usually worse than the news that causes up gaps is good, and the sessions that follow are faster and less orderly. The shape is the same; the tempo is not.
- A specific cause — a guidance cut, a failed trial, a lost contract — rather than general weakness.
- Opening volume at a large multiple of normal, sustained past the first half-hour.
- A first-half-hour range that sits well below the previous range and does not climb.
- No serious attempt to reclaim the bottom of the previous range at any point.

Why it forms
An overnight repricing this large leaves every holder owning something worth materially less than it was, and it leaves them owning it without having had any chance to react. The opening range is where they get that chance.
If the range holds low and volume stays heavy, the answer is that they are taking it — that supply is still arriving at prices well below yesterday's, and nobody is stepping in front of it. That is why the volume behaviour matters more here than in almost any other set-up: a down gap that goes quiet has stopped being sold, and a down gap that keeps trading heavily has not.
The distinguishing question is what fell. A company-specific repricing is a permanent change to the thing being valued and there is no particular reason for it to reverse. A gap driven by a broad market shock is a change to the mood, and moods recover — which is why the same shape on the same chart means two different things depending on what caused it.
| What to look at | Set-up intact | Set-up failing |
|---|---|---|
| The opening range | Low, tight, and no attempt to climb | Rising steadily off the opening low |
| Volume after the open | Heavy well past the first half-hour | Fading as price recovers |
| Distance recovered | A small fraction of the gap at most | A third or more back within the hour |
The price points that define it
A set-up is a shape plus a handful of prices. The shape is what makes it recognisable; the prices are what make it something that can be measured, reviewed afterwards and argued about honestly. These are the levels this one is read from.
| Level | Where it sits | What it tells you |
|---|---|---|
| The prior close | The last price of the previous session | The top of the gap, and the price a full recovery would return to. The distance to it is the size of the squeeze this set-up risks. |
| The prior range low | The bottom of the range price gapped out of | The level that has to hold as resistance for the repricing to be more than a day's panic. |
| The opening range low | The low of roughly the first half-hour | The price the set-up completes through, and the level that says supply is still arriving. |
| The opening range high | The high of the same period | Where the reading stops holding. Above it price is recovering the gap rather than extending it. |
Where the set-up completes
- 1The triggerThe set-up completes on a move through the opening range's low, once that range has finished forming — the same fifteen or thirty minute conventions apply, and the same rule that the window is chosen before the open rather than after. A break of a range that is still being built is not a break.
- 2Where the reading stops holdingThe reading stops holding above the opening range's high. Above it the session is recovering rather than extending, and because the gap above is unfilled there is nothing structural between that level and the previous close, which is exactly why the failure of this set-up is so much faster than its success.
- 3The measured objectiveThere is no scaled objective available. The conventions borrowed for it — the gap projected downward, a multiple of the opening range, the next prior low — are all arbitrary here, and a set-up with a firm invalidation and no target is a more honest description than a set-up with an invented one.
- 4Through the moveThe convention watches volume and the shape of the recovery attempts. Each rally that fails lower than the last says supply is still ahead of demand. A rally that clears the previous attempt is the first evidence that the sellers are finished, and it typically arrives before the opening range high is reached.
Each of these describes where a convention puts a level, not what anybody should do at it. Whether a level is worth acting on at all is a question about position size, cost and the rest of a plan, and the answer differs for every account.
How often it follows through
The lowest band in the catalogue, and deliberately so. Down gaps produce the sharpest reversals of any shape here, because a market that has already fallen a long way in one move has removed most of the supply that would slow a recovery. Company-specific gaps sit at the top of the band; market-wide ones sit at the bottom.
Read that as a floor rather than an expectation. A set-up that follows through two times in three still leaves one in three that does not, and the one that does not can move further and faster than the two that did. That arithmetic is what position sizing exists to answer, and no pattern improves it.
What this number is not
It is not our record, it is not a forecast for any particular chart, and it is not the rate at which the measured objective is reached — that is always lower. It is a conservative reading of how often a completed gap-down continuation kept going before it went back through the level that invalidates it. Base rates move with the market, the timeframe and the exact definition used, and every one of those varies.
What failure looks like
The failure is the reclaim, and it is fast. Price stops making new lows, the opening range high goes, and because the gap above is empty of any structure, price travels back through it with very little to slow it down. A recovered down gap frequently finishes the session near the previous close, which means the failure of this set-up covers as much ground as its success would have.
- Each attempt at the opening low is shallower than the one before it.
- Volume thins on the down moves and builds on the recoveries.
- A third of the gap is recovered inside the first hour.

Seeing it on a live chart
The question this set-up turns on is not on a chart at all: what caused the gap. Read the release beside the chart, because a guidance cut and a market-wide risk-off morning produce the same picture and behave nothing alike for the rest of the week.
